STREET-RAILWAY CONSTRUCTION.

SPECIFICATION forming part of Letters Patent. No. 375,852 dated January3, 1888.

Application filed October 10, 1887. Serial No. 251,888. (No model.) I

To all whom it may concern:

Be it known that I, REYNOLDS T. WHITE, a citizen of the United States,residing at Boston,,in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Street-Railway 0011struction; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

The object of my invention is to constructa substantial and economicalstreet railway road-bed; and it consists in the certain details ofconstruction of the rails, ehai rs, and sleepers, and the peculiar wayof holding the rails in the chairs, as hereinafter fully described, andparticularly pointed out in the claims.

Referring to the drawings, Figure 1 represents an end view of agirder-rail secured into a metal chair by a key, the chair being securedto a wooden sleeper. Fig. 2 represents an end view of a girder-railkeyed into a combined chair and sleeper. Fig. 3 is a horizontal sectiontaken on line X X of Figs. 2 and 4. Fig. 4 is a side view of the same.Fig. 5 represents the ends of two adjacent rails keyed into one chair.Fig. 6 represents a Vertical cross-section of a combined chair andsleeper, one side being cut away to show the keyway. Fig. 7 represents akey drawn to an enlarged scale.

A represents a rail of any desired form of tread, having a rib, B, onits under side at or near its center, the rib B being provided with aslot, 0.

D is a chair of metal and of the form shown, secured to a woodensleeper, G, by spikes or lag-serews. The chair D is provided with akeyway, E, cast therein, as shown, so that when the rail A is laid inthe chair and the key F driven in the rail A is drawn down solid ontothe top of the chair D.

In Fig. 5 I have shown a chair to be used at joints of adjacent rails.This chair is of suitable width and provided with an opening, H,

through its center, so as to get at the ends of the keys F, should it bedesired to drive them out or to turn their points up.

It will be seen that when the chairs are made to set on wooden sleepersthey are spread at the bottom and provided with ribs,as shown in Fig. 1,so as to stiffen and keep the rails from what is termed rolling whenheavy teams are passing in or out or over the track; but when an ironsleeperis used the chairs and sleeper are cast in one piece and of therequired length to form a gage for the rails and about the form shown,so that the paving can come up close to the rails and not interfere withthe sleeper or chair. The end of each rail is recessed or hollowed out,so that when the ends of two adjacent rails are placed to gether in thechair an'opening will be left through which a key-bolt is passed, andwhen the key is inserted in the bolt it clamps the chair to the webs ofthe rails, and the keys F F draw the rails down, preventing any side orupward movement of the rail, but at the same time allowing the rail toexpand or con tract. I

Having thus described my invcntion,what I claim is 1. A street-railwayrail, A, having a tapering rib, B, on its under side at or near itscenter, said rib being provided with a groove, 0, in combination with achair, D, provided with an opening to receive said rib, and ataperingkeyway, E, and the key F, substantially as and for the purposes setforth.

2. A metal chair spread at its bottom transversely from the rails andprovided with an opening adapted to receive the rib of the rail, andtapering keyways, in combination with a rail having a tapering rib at ornear its center on its under side, said rib being provided with a grooveon one of its sides and capable of being keyed into the chair,substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
